Both labels are often applied to anyone who dates a heavy person but isn't overweight themselves, regardless of any other qualities they like in the person or if they simply find that person attractive with no particular fetish.

In one of the Filler episodes of Naruto, there's a princess who hires Ino to pose as her during a meeting with her fiance until the princess loses weight. It turns out, however, that the prince likes his women pudgy (he's a big guy himself).

Ranma ½: This trope is referenced and combined with the You Are Fat trope for hilarity when Ranma's mirror clone tells Akane that Ranma likes her.

Deadpool is one and even goes on a date with Great Lakes Avengers' Big Bertha. He is so blatant about it that she tells him she feels as objectified as when she's in super-model mode, and wishes that people could look beyond her physical appearance and love her for her personality. Deadpool then takes his mask off to take her up on the offer... then comes her Vomit Discretion Shot.

Jimbo from Rose Is Rose prefers Rose if she were fat, so much that he often looks through wide reflections of her to fantasize about it.

"Excuse me, I am tired of living a lie. I need it to be known that I like a big girl. In fact, a large, zaftig, voluptuous, full-figured, big-boned, massive-assive honey, that is what gets me going. I like fat women and they like me... big girls need love too, baby!"

The story "The Illustrated Woman," in Ray Bradbury's The Machineries of Joy, features a man named Willy Fleet who, when he first encountered his plus-sized wife, rhapsodized that "Michaelangelo would have loved you. Titian would have loved you. Da Vinci would have loved you. They knew what they were doing in those days. Size. Size is everything."

In the Discworld series, the Senior Wrangler of Unseen University is implied to be one. In Hogfather he tries to court the plump and somewhat frumpy Cheerful Fairy, and in The Last Continent he's frequently distracted by thoughts of Mrs. Whitlow, the University's fat, middle-aged head housekeeper.

In Just Shoot Me S04-E13 Dial 'N' For Murder, Maya is happy that she has started dating a man who dislikes the waif-thin look that her father's fashion magazine promotes. Unfortunately, she discovers that while she agrees with him, she doesn't want to let him fatten her up.

In Bones S5-E08 The Foot In The Foreclosure, the Victim of the Week was a former chubby girl who had been a regular at a Chubby Chaser hookup bar. After she lost the weight, she went back as a chaser.

Cheers: A hot woman goes after Norm, to the befuddlement of the others at the bar (especially Sam). Paul (one of the minor characters who had an occasional Day in The Limelight, and who is also a chunky guy) identifies her as a "chubby-chaser."

In Todd and the Book of Pure Evil S01-E05 Monster Fat, Jimmy the Janitor mentions having slept with hot chicks, skinny chicks and even chicks with dicks. But the best sex of all is with fat chicks. Notably, the episode where he imparts this insight to the main character feature a Monster of the Week turning all the female students obese.

"When I want to grease my piece, I go obese."

In fact, one of the plot points of the episode is using a water pistol full of the instant obesity liquid to threaten the girl who accidentally made the fat monster. At the end of the episode, we see the Janitor on a date with an extremely attractive woman. When she leaves to visit the bathroom, he immediately produces another water pistol and squeezes it into her drink.

One episode of House has a husband admitting that he loves it when his wife puts on a few more pounds, especially whenever she becomes pregnant. For that matter, the wife likes her curvier body and downright becomes angry when the doctors told her that she needed to do a surgery that would cause her to lose weight.

Hal of Malcolm in the Middle goes off the deep end when a pregnant Lois grows a few sizes. He spends a whole episode injecting maple syrup and chocolate sauce into her tea and, when she buys celery, fries it in bacon grease.

Noah's Arc: Alex (a self described Big Beautiful Man) hints that Trey may be this, but since Alex is the only guy we see that Trey has an interest in, its difficult to assess.

One sidequest in Yakuza 4 is, basically, a hunt for a Chubby Chaser. Akiyama's chubby-yet-cute secretary has suddenly gotten all depressed, and claims that no man would be interested in her (not that she's really outright fat - by American standards, anyway), prompting Akiyama to try and prove her wrong by tracking down a man who likes 'em chubby. After some false starts, he finds one - working as a 'recruiter' for a Hostess Club, though not for long since his boss is fed up with him always bringing back the BBW's instead of the lithe beauties that such clubs generally deal in. In the end, even though you convince this fellow to come back to your office, and introduce him to Hana-chan, it fails to noticeably improve her mood... since the reason for her depression is that she's in love with Akiyama, who—aside from being a hopeless playboy—has a decided preference for the traditional, slim body type.

In one quest in Morrowind, the player must find a prospective wife for a dark elf noble, and according to him, she should be "pretty and plump, with big hips."

In Fable II, some of the NPCs in the Knothole Island DLC are "fat-loving", and will find your PC to be more attractive if they're overweight, rather than less attractive.

Pam from Archer is targeted by a rich German Chubby Chaser in one episode, much to Malory's disgust, as she was trying to seduce the man for her own agenda. They eventually get drunk and have a threesome anyway.

Family Guy: When Lois slowly becomes obese, Peter discovers that he's a chubby chaser. After she gets surgery to remove the excess weight, he's discovered having sex with the discarded fat. "Um...this is exactly what it looks like."
